Clean Energy

Solar energy is environmentally friendly technology, a great energy supply and one of the most significant renewable and green energy sources. It plays a substantial role in achieving sustainable development energy solutions. Therefore, the massive amount of solar energy attainable daily makes it a very attractive resource for generating electricity. Both technologies, applications of concentrated solar power or solar photovoltaics, are always under continuous development to fulfil our energy needs. Hence, a large installed capacity of solar energy applications worldwide, in the same context, supports the energy sector and meets the employment market to gain sufficient development. This paper highlights solar energy applications and their role in sustainable development and considers renewable energy’s overall employment potential. Thus, it provides insights and analysis on solar energy sustainability, including environmental and economic development. Furthermore, it has identified ...

The role of science, technology and innovation in increasing the share of renewable energy worldwide

2021

A number of countries in the emerging markets are becoming leaders in manufacturing solar photovoltaic products. Thus, global companies are urged to compete in all stages of the supply chain for producing most of the installed solar modules around the world. Meanwhile, production costs are at record lows. The decisions made in the emerging markets will affect the course for the solar and wind industry and their role towards de-carbonization of global energy systems in the near future. Renewable energy is set of miscellaneous natural resources, which preserves non-renewable sources for further use in other sectors of the economy, and saves green energy for future eras. The way a country employs its potential in renewables will safeguard the country’s energy security and the stability of electricity prices. Renewable energy is eco-friendly, as its operation does not produce any waste, or discharge pollutants into the atmosphere or water bodies. Our paper discusses the latest achieveme...

Green Energy Strategies Towards Sustainable Development for Environment and Society

Zenodo (CERN European Organization for Nuclear Research), 2023

In the year 2020, fossil fuels, led by coal, natural gas, and oil, will contribute 61.3% of the world's electrical production, posing the greatest sustainability problem currently facing humanity. The world's energy needs are currently outstripping available generation capacity by a wide margin. Thus, it is necessary to effectively and securely meet future energy demands. Use of renewable energy sources should be a component of energy solutions. To meet the world's primary energy and electricity needs at the moment, renewable energy sources do not contribute significantly enough to the primary energy supply. Fossil fuel dependence will unavoidably persist in the ensuing decades in both industrialised and emerging countries. The issue is worse in developing nations than it is for developed countries. It appears that many emerging nations have been attempting to reform their energy industries. It appears that implementing innovations is challenging. The three biggest obstacles to the development of renewable energy are price, market share, and policy. Numerous nations have energy policies that assist sustainable development in connection to factors like the economic, social, and industrial ones.

The three biggest obstacles to the development of renewable energy are price, market share, and policy. Numerous nations have energy policies that assist sustainable development in connection to factors like the economic, social, and industrial ones. Introduction: The need for energy is growing incredibly. The industrialised nations account for 28% of the global population and 77% of global energy production, as shown in [1]. The current global population is projected to grow by 1.26 times by 2050, reaching 9.7 billion people. The majority of the world's population, including 90% of population increase, is found in emerging nations. The industrialised nations' energy usage won't rise by 2050 despite the adoption of increasingly effective energy saving measures. People generally want to build their own electricity-generating facilities in emerging nations, nevertheless. One of the biggest and most significant challenges facing humanity in the twenty-first century is the decarbonization of the world's energy systems. Since the energy industry produces nearly two thirds of the world's carbon dioxide, it is essential to combating climate change.Electricity and other basic energy sources are what fuel the global economy's growth [2]. By the year 2020, the combined proven energy reserves of the three main fuels-oil, natural gas, and coal-could only last 53.5 years for oil, 48.8 years for natural gas, and 139 years for coal. 85% of the world's total primary energy consumption comes from these fossil fuels. The most significant environmental challenge of our time is global warming, so cutting carbon emissions is at the core of international environmental policy.[3] It is also

A comparison of electricity production technologies in terms of sustainable development

Energy Conversion and Management, 2012

The electricity production sector has currently and for the past years been dominated by fossil fuel technologies, mostly coal, oil and natural gas. This has had various environmental consequences, such as increased gaseous emissions, soil and water pollution, global warming, as well as fossil resource depletion. As a result, the need to pursue Sustainable Development (SD), in order to reduce dependency on fossil fuel, to achieve Greenhouse Gas (GHG) mitigation and to reverse the effects of climate change has currently become imperative. SD is considered to be one of the most important factors for countries' energy policy today and efforts, such as the ones materialized through the Kyoto Protocol mechanisms, are being made to promote sustainable electricity production technologies globally. Nuclear and renewable energy technologies both have the potential of contributing to the increasing global energy demands, while simultaneously lowering GHG emissions and also having a positive economic and social impact. In view of their differences and the ongoing nuclear debate, this paper aims to compare specific promising and emerging nuclear and renewable energy technologies in terms of their contribution to SD and prospects for deployment. The comparison showed that each technology contributes in its own way to SD and that political decisions, individual country energy policies and public opinion will probably determine the future deployment of each energy technology.

Potential of solar energy in developing countries for reducing energy-related emissions

Renewable and Sustainable Energy Reviews, 2018

The growing global demand for energy from fossil fuels plays a key role in the upward trend in greenhouse gas (GHG) emissions and air pollutants. Rapid population growth and increasing energy demand in the developing countries have brought many concerns such as poverty, pollution, health and environmental problems. While for these countries, particularly the poorest ones, modern energy is necessary to stimulate production, income generation and social development plus reduce the serious health issues that are caused by the use of fuelwood, charcoal, animal dung and agricultural waste. Solar energy is the best answer to energy poverty and it can provide excellent opportunities for reduction of GHG emissions and indoor air pollution through substituting kerosene for lighting and firewood for cooking. Solar photovoltaic (PV) can be an appropriate technology for a source of renewable electricity in developing nations especially in remote rural areas where grid extensions are financially or technically not viable. PV can also be used to reduce demand for fossil fuels and associated emissions, including carbon dioxide (CO 2) , nitrogen oxides (NO x) and sulfur dioxide (SO 2). The use of PV systems can reduce 69-100 million tons of CO 2 , 126,000-184,000 t of SO 2 and 68,000-99,000 t of NO x by 2030. In case countries use concentrating solar power (CSP) systems, each square meter of concentrator surface is enough to save about 200-300 kg (kg) of CO 2 emissions annually. Although there are excellent renewable opportunities in many developing countries, several key barriers have prevented large-scale deployment of solar energy technologies in these countries. This study reviews the sources of energy-related emissions, risks of climate change, global solar energy potential, sustainability indicators of renewable energies, environmental impacts of fossil fuels and renewable energies, benefits of solar energy utilization. It also discusses barriers to widespread use of solar energy.

Green Energy Sources for Sustainable Development and Environmental Protection

The consumption of energy has been increasing rapidly and in fact almost exponentially since the Industrial Revolution. To meet the growing demand of energy, there is at present the pressing need of alternative sources of energy in order to partially solve the present-day problems of the use of fossil fuels. The target is then to explore such energy system or systems that have no negative environmental, economic and societal impacts, which we mostly refer to as “green energy”. The sources of green energy include the energy from sun, wind, biomass, geothermal, hydropower system etc. which will provide an important attribute for sustainable development. This article explains the practical relevance of deriving the energy from sources like ethanol, methanol, biodiesel, hydrogen energy, solar energy. Increasing the utilization of the sources of green energy to a maximum extent will definitely benefit the mankind in terms of their reliability and environmental protection ability. In view of this, an attempt is made to study the applicability of these green energies in our day-to-day life for sustainable development and environmental protection.

Renewable Energy for a Clean and Sustainable Future

Http Dx Doi Org 10 1080 00908310490441421, 2010

This article discusses the growing need of energy in both developed and developing countries, and the acute population growth, which will exceed 10 billion by the year 2050. How can a world of 10 billion people be provided with adequate supplies of energy, cleanly, safely and substantially? There is a growing consensus that renewable energy sources will be a very important part of the answer. The growing interest in renewables has been prompted, in part, by increasing concern over the pollution, resource depletion and possible climate change implications of our continuing use of conventional fossil and nuclear fuels. Recent technological developments have also improved the cost-effectiveness of many of the renewables, making their economic prospects look increasingly attractive. It describes the achievement and progress made in hydropower, biomass conversion, geothermal, solar thermal technology, wind energy conversion, and the increasing usage of photovoltaics. It is evident that global warming is setting in and is going to change the climate, as well as the terrain of many countries, unless drastic measures are taken. The Kyoto meeting emphasized the importance of limiting CO 2 emissions and to abide by some form of agreement to reduce emissions. The present study concludes that renewable energy penetration into the energy market is much faster than was expected in recent years and by 2030, 15-20% of our prime energy will be met by renewable energy.

THE AWERNESS OF SUSTAINABLE DEVELOPMENT POLICY ON SOLAR ENERGY USAGE

International Journal of Engineering Technology Research & Management (ijetrm) , 2019

Electricity plays a crucial role in the development and use of Information and Awareness in the process of striving to achieve sustainable development in emerging economies. It has been shown that electrical energy is intrinsically linked to economic, environmental and social dimensions of sustainable development. The demand for electricity in residential, commercial and industrial sectors in developing countries is likely to increase, both as a result of increase in population and expanding industrialization. It remains amongst others, a growing challenge for these nations to obtain and put in place reliable and secured electricity supplies, for accessing Information and Awareness and to work towards achieving sustainability. To address some of these challenges without compromising the goal of sustainability and development, it is important that low carbon emitting electrical energy sources such as solar electricity are given high priorities by policy makers, industries and R&D institutions in emerging countries. Solar electricity is of major interest for the energy sector in developing or emerging economies because it offers the possibility of generating renewable electricity using sunlight-a resource that is widely and free available in most if not all developing countries. This paper aims to systematically examine and draw attention to potential benefits of solar power generation for access to and use of Information and Awareness aimed at sustainable development in emerging economies. Specifically, the paper provides an extensive analysis of the major contribution of solar electricity in various sectors such as economic, social and environmental benefits. We point out the important issues that must be considered and addressed for the successful implementation of solar electricity programs for sustainable and development in developing nations. The paper concludes with a discussion on current status of solar electricity in major emerging economies, their planning policies and strategies for promoting solar power generation for increased access to Information and Awareness by people and sustainable development of society. KEYWORDS: Sustainable development policy, Information and Awareness and Solar Energy INTRODUCTION Apart from land, capital and labour, electrical energy is a crucial input in the process of sustainable development in emerging economies (Brazil, Russia, India, China and South Africa). It has been shown that electrical energy is intrinsically linked to environmental, social and economic aspects of sustainable development. However, for the past decades, the electrical energy demands in emerging economies have been met by non-renewable energy sources (specifically coal, thermal, oil and gas) which are pollution agent, not equally distributed and worse still, limited. On the other hand, the demand for electrical energy for technological use and sustainable development in emerging economies is likely to increase, both as a result of increase in population and expanding industrialization. The need for emerging economies to address climate change and increase its reliable, affordable, clean and secured electrical energy supplies, in both urban and rural areas, is a key challenge which requires market penetration of low carbon emitting energy technologies. Solar electricity (from photovoltaic) is clearly one of the most promising prospects to the problems since it is non-pollutant, renewable and sunshine is available to all emerging economy countries, although with varying intensity.
